MASS REARING OF THE CARROT WEEVIL, LISTRONOTUS OREGONENSIS (COLEOPTERA: CURCULIONIDAE), UNDER CONTROLLED ENVIRONMENTAL CONDITIONS
Keyword(s):
AbstractA technique for mass rearing the carrot weevil, Listronotus oregonensis (LeConte), is described. Adults were provided with carrot roots for food and oviposition sites. Larvae developed directly in these roots. Different temperature regimens for larval rearing were tested and best results were obtained using 21 °C for the first 2 weeks of larval development and 27 °C thereafter. Photoperiod was maintained at 16 h and relative humidity at 70%. Under these conditions, 97.6% of adults emerged in 39–42 days.
